But i have just realised something. Take a quick look at goliath, Now take a look at Behemoth. Look familiar?

I believe Behemoth is just an Mega evolved (Yes i do like pokemon)

1: Both have exactly 3 fingers

2: Look at the skin under the behemoths rocks. Pinkish grey exactly like a damaged goliath.

3: Look at the top of behemoth. See how it has some broken spikes? Notice the placement of the spikes? A stage 3 goliath has basically the exact same spikes. The only difference is Behemoths is broken.

4: Both goliath and Behemoth both have tusks

5: And the most important part. Look at both goliath and behemoths necks. Both have gills or scratches.

I would imagine, much like the native species of our planet, that the Monsters of Evolve share common ancestors. Goliath and Behemoth could be two different descendants, or evolutions of , the same ancient creature.
